Elnur’s SH18-M 2.4kw Manual Static Storage Heater consumes energy during off-peak hours* when rates are at their best, and releases heat gradually so you can enjoy a comfortable temperature all day, not to mention lower electricity bills. This efficient appliance releases heat in two different ways: a primary convection controlled by a top flap that opens after the storage heater is charged and a secondary convection which releases hot air 24 hours a day. To ensure maximum performance, the SH18-M features high-quality materials, including three types of cutting-edge thermal insulation and magnetite storage blocks, which offer the highest heat storage capacity available. It also offers a damper control device and a charging thermostat with a phial.
